Aggregator Host

I went on task manager saw this thing called "Aggregator host" and then pressed the delete key on it and now its gone, I read that it was a bitcoin mining malware thing, and now I'm starting to reconsider. If its safe how do I get it back?? On windows settings it still has all the computer health stuff checked and good, but I'm just worried.

how do we get list of aggregations which are unused on the cube ?

Sql server version: 2016

Is there a way to know if aggregation on the cube is unused ? I have tried to get the information on the DMVs $system.discover_object_activity (gives me count of aggregations on a partitions/measure groups being hit or missed) and $system.discover_partition_stat
(aggregation name and its processed state). But I am not able to get information if a aggregation is left unused, like a list of aggregations which have been used/unused

The cube which is being investigated has over 200 aggregations. It is cumbersome to manually go through each one of them and check for the combinations. Any help is appreciated.
